On the internet, nothing is safe — not even your DNA, apparently.

That’s the dystopian lesson from the commercial genetic testing company 23andMe, which disclosed on Friday in a regulatory filing that hackers managed to access information on about 14,000 users or 0.1 percent of its customer user base.

But the problem goes beyond this relatively small number of people. Because the website allows users to share DNA information with other users in order to find relatives, the true number impacted is orders of magnitude larger — with about 6.9 million customers having their personal information compromised, according to TechCrunch. Big yikes on that figure, because it affects something like half of the 14 million users at 23andMe.

Researchers find the brain structure is crucial for informing us where are bodies are and what they’re doing.

Elon was left “speechless” when confronted with the possibility that AI could follow humans to another planet.

An MIT spinoff co-founded by robotics luminary Daniela Rus aims to build general-purpose AI systems powered by a relatively new type of AI model called a liquid neural network.

The spinoff, aptly named Liquid AI, emerged from stealth this morning and announced that it has raised $37.5 million — substantial for a two-stage seed round — from VCs and organizations including OSS Capital, PagsGroup, WordPress parent company Automattic, Samsung Next, Bold Capital Partners and ISAI Cap Venture, as well as angel investors like GitHub co-founder Tom Preston Werner, Shopify co-founder Tobias Lütke and Red Hat co-founder Bob Young.

The tranche values Liquid AI at $303 million post-money.

Submerged beneath a manmade lake in China lies a forgotten city, dubbed by experts as “China’s Atlantis”

The underwater city, known as the Lion City or Shi Cheng, is hidden 40 metres beneath the surface of Qiandao Lake in eastern China.

One of nature’s most common organic materials—lignin—can be used to create stable and environmentally friendly organic solar cells. Researchers at Linköping University and the Royal Institute of Technology (KTH) have now shown that untreated kraft lignin can be used to make solar cells even more environmentally friendly and reliable. The study has been published in the journal Advanced Materials.

Sunlight currently seems to be one of the main sustainable energy sources. Traditional solar cells made from silicon are efficient but have an energy-demanding and complicated manufacturing process that may lead to hazardous chemical spills. Organic solar cells have therefore become a hot research area thanks to their low production cost, light weight and flexibility, and hence have many applications, such as indoor use or attached to clothing to power personal electronic devices.

But one problem is that organic solar cells are made of plastic, or polymers derived from oil. So, although organic, they are not as environmentally friendly as they could be.

Physicists at the University of Regensburg have found a way to manipulate the quantum state of individual electrons using a microscope with atomic resolution. The results of the study have now been published in the journal Nature.

We, and everything around us, consist of molecules. The molecules are so tiny that even a speck of dust contains countless numbers of them. It is now routinely possible to precisely image such molecules with an atomic force microscope, which works quite differently from an optical microscope: it is based on sensing tiny forces between a tip and the molecule under study.

Using this type of microscope, one can even image the internal structure of a molecule. Although one can watch the molecule this way, this does not imply knowing all its different properties. For instance, it is already very hard to determine which kind of atoms the molecule consists of.

“It is particularly challenging, expensive, and time-consuming to find polar bears in the Arctic, let alone count them and understand how they are coping with climate change,” said Dr. Melanie Lancaster.

Can scientists use DNA from polar bear footprints to help improve conservation efforts during this age of climate change? This is what a recent study published in Frontiers in Conservation Science hopes to address as a team of international researchers have developed a novel tool designed to use DNA from polar bear footprint skin cells with the goal of tracking the large mammals without the need to capture them, which often risks the safety of both the polar bears and their human captors in the process. This study holds the potential to develop new methods in tracking animals whose populations are at risk as climate change continues to warm the planet.
